FABRIC STEAMING AND STRETCHIITGMEANS.

Application filed December 2, 1926. Serial No. 152,227.

gMy invention relates to the steamingand Stretching of tubular fabrics and ismore parcticularly intended for embodiment in an apparatus forstretching tubular fabrics.

The generalyobject of iny invention is to provide asteamingand stretching device .,-that will result in a uniform stretching of the-fabric. without distortion of the design.

--pres ented by.,the fabric, as wellas to-make sprovisionfor adapting the device to stretching tovarying degrees.

,, The nature ofemy invention audits distinguishing features and advantages willv clearly, appear as the description proceeds.

Reference is to be ;had to the accompany wingdrawings forming a part of this specr,

- fication, it'being understood thatI-the drawingsaremerely illustrative of one example of the invention.

F gure 1 is a side elevation of a steaming and stretching device'embodying my present invention.

Figure 2 is a transverse vertical section ttS*,1I1dllCa.t8Cll3y: the line 2 2 in Figure 1.

Figure 3 is a detail in horizontal section as indicated by the line 3-3 in Figure 2 and looking in the direction of the arrows.

In carrying out my invention in practice in accordance with the illustrated example, a hollow body is provided, said body being cylindrical, oval or other shape.

The bottom 11 of body 10, in the form of a disk or plug, has a steam inlet nipple 12 which extends into the upper end of a vertical tubular steam pipe 13, leading to which is an inlet pipe 14 adapted to connect with any convenient source of steam supply. The steam pipe 13 rises from any suitable base 15.

Within the hollow body 10 is a vertical steam pipe 16 having outlet orifices 17 at the upper end. Said pipe 16 rises from the bottom 11 of the body. Supported on the pipe 16 is a bell 18, the lower edge of which is spaced from the bottom 11. Said bell 18 is here shown as held to cap 116 on pipe 16 by a screw 19. The body 10 has an annular series of steam outlets 20 formed therein above the bottom of the body.

On the body 10 at the top is a spreader 21 for the fabric, indicated by dot and dash lines at A. The purpose of the spreader 21 is to give the tubular fabric the form of a flattened tube, so that the fabric may be folded or formed into a roll. Said spreader 21 is in the form of a loop somewhat wider than the body 10. The lower end has inturned terminals secured to a. base bar 22 which 1s partly accommodated in, a itransverse groove 23 in a, cap 24- of aplug 25 forming a closure oftheupperend ,ofabody 10., A screw or bolt 26 passes: thr,ough.--base 22 and cap 24 and intoithe plug 25.. v.Byloosening the screwv 26 the base 22-and-spreader 21 ,may beturned about the axis-of said screw to dispose the.. sp reader sin various angular positions above the body 10.

The steam pipe 13 has a collar or flange 27 thereon at the uppenend which i iheld to the arm 11 of body 10 byswingbolts 28. In theillustrated example Iprovidefor the convenient detachment of of body 10 from the pipe 13. The swing bolts 28fare aali iOVVn expedient and swing into; notches in .the opposite sides of flange 27.

1 The tightening of nuts 30 onthe bolts 28 serves to tightly press the pipe '13, and its collar 27 against apacking iii-interposed at the underside of the bottom 11' of the body 10. i

The numeral 32 indicates afdrain passage in the bottom 11, said passage leading to a dram pipe 33 to carry off the water of condensation from the body 10.

An annular band or ring 35 is detachably secured about the body 10, preferably by forming the body with an annular bead 0r beads 34 on the two sections from which the body is formed. The beads 3 1 con stitute flanges on the body sections united by screws 134. By providing for detachably a securing the spreading ring 35, rings of various sizes may be emplaced according to the degree of stretching to be given to the fabric. Rings may be employed of a size,

for example, to stretch the fabric from twenty inches to thirty, thirty-five, forty inches, for instance.

For the purpose of detachably securing stetching ring 35, use is made in the present example of screws 37 adapted to engage in keyhole slots 36 in said ring.

With the described arrangement, after removal of the body 10 with its spreader 21, from the pipe 13, the fabric is passed downwardly on to said pipe 13 and gathered thereon. Then the body 10 is again attached to the said pipe 13 and the fabric is drawn upwardly over the body 10 and spreader 21. With the fabric A in position, steam is admitted 'to pipe 13 and passes upwardly through nipple 12 to interior pipe 16, from which the steam escapes through the openings 17 into the bell 18. The steam is distributed throughout said bell 18' and escapes from beneath the lower edge thereof to the exterior of the bell and passes out wardly through the jet orifices 20 against the interior of the fabric A beneath the stretching ring 35. The steam, by filling the space at the interior of the fabric directly beneath the ring 35, acts as an agent to improve the fabric and soften it, thereby preparing the fabric for easy stretching. The space is maintained with amplesupply of steam escaping from the openings 20, so that the fabric is continually, and uninterruptedly subjected to the action of the steam escaping from said orifices 20.

The fabric is drawn upwardly over the body 10 and spreader 21 after the steaming. The bell 18 is in the lower portion of body 110 and the fabric, in passing over the body 10 above the plane of the top of hell 18 is subjected to a drying action, the drying continuing as the fabric passes over and from the spirit of the invention, as defined in the may be drawn for steaming said body having an annular series of steam outlet openings, a bell within the body, said bell being closed at the top and open at the bottom, a steam pipe extending into said bell and formed with steam outlets near the top of said bell and means to direct steam to said steam pipe, together with means at the top of said steam pipe and affording support for the bell at the top of the latter. V i

2. A stretcher including a hollow body over which a fabric may bestretched, a fabric spreader-on sa-idbody at'the top, a transverse element at the bottom of said spreader and to which the sides of the spreader are secured, an element'constituting a closure of said body at the top, a separate member on said closure element, said transverse element being seated on said sepa rate member, and a screw extending through said transverse element and through said separate member and into said closure element, said screw being adapted to be tightened or loosened for turning the said separate member and the spreader about the vertical axis of said screw.
